NITED STATES PATENT Onnrc lCE-CRUSHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 247,713, datedSeptember 27, 1881.

Application filed March 22, 1880. (No model.)

To all whom it may concern Be it known that I, WILLIAM TUNSTILL, of Yonkers, in the State of New York, have invented an Improvement in Ice-Crushing Machines, of which the following is a specification.

I construct this machine with reference to the convenient separation of the parts for repairs, so that any one part can be taken out without disconnecting the frames. This is of great importance in this class of machines, be-

- cause they are usually placed in cellars and other'cool places where the parts are liable to become rusty, and from which cellar the entire machine cannot be easily rem oved to a machineshop for repairs.

I provide a stationary and a moving jaw, between which the ice is cracked, and from thereit falls between revolving toothed rollers. There is a pushing-plate that delivers the ice from beneath the in achine, and this is actuated by the moving jaw. The shafts, rollers, and gearing are removable from the plates or frame of the machine, so that they can easily be taken out for cleaning or repairs.

In the drawings, Figure l is a vertical section of the machine. Fig. 2 is a rear elevation, and Fig. 3 is a side elevation, of the frame and boxes, with the shafts in section. Fig. 4 is a sectional plan at the line 00 x.

The side plates, b, of the machine are of a size and shape adapted to the other parts, and are preferably of cast-iron. The stationary jaw a is bolted between these plates, and this, with the tie-bolt 2, connects the said plates 7) b firmly together.

The driving-shaft c is supported in thejournal-box'es d d, that are separate from the plates b and enter into notches or recesses in the front edges of the plates I), and. are secured by the flanges 3 and bolts. By loosening these bolts the shaft 0 and its parts can be taken away from the machine, or the reverse.

The shaft 0 is provided with fly-wheels c, and may be driven by hand or steam power. The wheel (1 gears into a wheel, ZZ on a shaft, 6, that is supported in journal-boxes 4, similar to the journal-boxes d, so that the same may be taken out by removing the bolts 5.

At the ends of the shaft 6 are disks 6, having crank-pins 6, from which the connectingrodsf pass to the cross-bar 7 of the moving jaw g.

The jaw g has arms 8, that extend to the rear, and through which the shaft 9 passes, and on which shaft the jaw g is swung, and the ice that is placed within the. hopper formed by b b,a,and g is crushed by the movement of the jaw, and falls away from the mouth at the bottom of the hopper upon the crushing-rollers h h. The lower edge of the moving jaw rises and falls considerably as the jaw is vibrated. This not only opens the mouth ofthe lower end of the crushinghopper to allow the ice to fall down freely, but the teeth on the lower part of g serve to rake the ice down that might otherwise pack in and injure the hopper.

The shaft 9 is supported at its ends by the movable journal-boxes 12, that are screwed upon the surface of the plates 1) b to allow of their adjustment or removal, so as to take out the shaft and jaw, if necessary. The slots that receive the bolts are elongated to allow of the journal-boxes 12 being adjusted to position.

The rollers h h are armed with teeth, that are pointed, as shown, so as to penetrate and break the lumps of ice and reduce them to a uniform size, or nearly so. The rows'of teeth that are upon the rollers h h are the same in their position lengthwise of the shaft, but the number of teeth in the rows on the roller h is much less than the number in the rows on h, so that the lumps of ice will fall in between the teeth in h and be broken by the teeth of the roller h.

The roller h is supported by the journalboxes 14 and 15, that are bolted to the plates 1) b, there being openings in the plates at these places, and the opening behind the box 15is large enough for the roller h or it to be passed endwise through the same, and this journalbox 15 is made with a flange or plate that is sufficiently large to cover said opening.

The roller his supported in the journal-boxes i, that are in horizontal openings through the plates-b, and hence said boxes can be moved nearer to or farther from the roller h,-to determine the size to which the pieces of ice are reduced. journal-boxes. They pass through the lugs 20, and are held by nuts, so as to adjust the roller h and retain it in position.

The train of gear-wheel's lconuects the shafts of the crushing-rollers h h, and allows of the adjustment aforesaid, and a rotary motion is The screws 19 are jointed to these given to the roller h from the driving-shaft c by the gear-wheels a.

Below the rollers h h there is a pushingplate, at, that is supported by and slides upon the ledges 21, that are upon theinner surfaces of the plates 1) b. This pusher has a vertical plate that serves to drive back the crushed ice that falls beneath the machine, and a horizontal plate near the under side of the crushingroller k, that prevents the ice falling behind the said pusher-plate.

The levers a have the cross-shaft 9 for their fulcrum, and at their upper ends they are attached t the movingjaw g, and at their lower ends there are links 1', that are hinged to the pusher-plate and give to the same a back-andforth movement in harmony with the crushing-jaw g.

I do not herein claim side frames with openings for the rollers to be passed in endwise, the same being shown in an application of like date herewith.

I claim as my invention 1. In a machine for crushing ice, the combination of plates b I), having notches at the frontedges, the stationary jaw a, the swinging jaw g, connecting-rodsf, shaft 0, crank-pins 6, and removable journal-boxes 4;, that are provided with flanges and. introduced into the notches at the front edges of the plates 1) b and bolted, substantially as set forth.

2. In an ice-crushing machine, the combina tion, with the stationary side plates, Z) b, hav in g openings through which the rollers can be passed endwise, of the rollers h h, removable journal-boxes 14 and 15, having flanges to cover the openings in the plates 1), the adjustable journal-boxes 'i, for the roller 7t, and the screws 19 and nuts, substantially as set forth.

3. In an ice'crushingmachine, the combina- 40 tion of the stationaryjaw, the moving jaw, the crushing-rollers, the pushing-plate, the levers connected with the movingjaw, and the links connecting the levers to the pusher-plate, substantially as set forth.

4. The combination, in an ice-crushing machine, of side plates, 11, stationary and moving jaws having teeth on their surfaces, the arms 8, shaft 9, and the mechanism for moving the jaw, the rollers h and h, having peripheral rows of teeth, the rows of teeth on one roller being more numerous than those on the other roller, for the purposes set forth, and a pusher and mechanism for reciprocating the same and removing the ice from beneath the rollers, as set forth.

Signed by me this 13th day of June, A. D. 1879.
